Solving “HHC6003: Error: The file Itircl.dll has not been registered correctly” – “Microsoft HTML Help Compiler 4.74.8702”

Posted by jpluimers on 2018/06/29

When generating the Spring4D documentation at https://spring4d.4delphi.com/ using Documentation Insight by DevJet, I got this error:

HHC6003: Error: The file Itircl.dll has not been registered correctly.
Microsoft HTML Help Compiler 4.74.8702

Solving it turned out easy:

regsvr32 "%ProgramFiles(x86)%\Documentation Insight 3\Compilers\CHM\itcc.dll"

I got there via [WayBack] HTML Help FAQ – Wiki.HelpMVP.com:

“HHC6003: The file itircl.dll has not been registered correctly”


This error effects only a small number of users. A HH component (c:\windows\system\itcc.dll) did not get installed or registered correctly. If not installed get the DLL from another PC containing Workshop. To register the DLL run
regsvr32 c:\windows\system\itcc.dll (this path may be different for your PC – eg. c:\winnnt\system32).

This fix was originally reported by MVP David Liske: [WayBack] http://www.mvps.org/htmlhelpcenter/itircl.htm
